Food occupies a role of particular importance in the consumer’s budget, especially in poor countries. This paper deals with special issues arising from modelling food consumption patterns in 138 countries, where per capita incomes differ by as much as a factor of 100. We explore various forms...

Building on purchasing power parity theory, this paper proposes a new approach to forecasting exchange rates using the Big Mac data from The Economist magazine. Our approach is attractive in three aspects. Firstly, it uses easily-available Big Mac prices as input. These prices avoid several...

The paper provides an account of aspects of exchange-rate economics that are of particular relevance to the resources sector. The issues discussed include exchange-rate volatility and risk management practices used to deal with it, the role of productivity differences across countries, the...

This paper analyses consumption patterns of vice -- marijuana, tobacco and alcohol. To deal with imperfect marijuana data, we exploit the interdependencies in the consumption of the three drugs identified in prior research, and introduce a Monte Carlo simulation procedure to formally account for...

Australian universities have in recent times been undergoing a substantial transformation in the way in which they are managed. They have moved away from the (British-based) traditional collegiate model to one in which professional managers play a centre-stage role. This paper investigates an...

This paper introduces an inverse differential demand system that has exactly the same form as the corresponding direct version. Its application is illustrated with the case of Australian fruit, whose prices were substantially affected by Severe Tropical Cyclone Larry in 2006.

Accurate and timely measures of cross-country real incomes are still a rarity. As the share of expenditure devoted to food is readily available, we use of Engel’s law in reciprocal form to measure affluence. Analysis of real income data for the OECD countries indicates that this approach is...

The Big Mac Index, introduced by The Economist magazine more than two decades ago, claims to provide the “true value” of a large number of currencies. This paper assesses the economic value of this index. We show that (i) the index suffers from a substantial bias; (ii) once the bias is...
